Lunar does the healer archetype differently. IIRC all the 'healers' are pretty brash but try to pretend to be 'pure and 'dainty'.
Pretending sounds interesting. I've seen villain healers with that personality trait. Never seen it in a hero party. Might be fun.
I'd like to point out that both of these are examples of the protagonist pulling out The Ultimate Attack, not the major villain. I'm not sure if that's relevant, but who knows, maybe it's just better done when it's the "hero" doing it?
To be fair, the ones where the hero does it in my example, the story has been set up in such a way to make us sympathize with the protagonist. "The Bride" in Kill Bill isn't really a hero. She's actually a villain. But, she's our point of view character and our protagonist who just wants something simple "revenge for killing my husband, putting me in a coma, and killing my child".
For the villain to pull off the "Ultimate Attack", you need to have some investment in the villain to start with and most media just... doesn't give you that investment in the villain.
That might be why I enjoyed the anime "Food Wars" to a large degree. Our hero LOSES a decent chunk of the time. His "opponents" or even the "villains" of some of the arcs actually TEACH HIM something. I find that to be pretty compelling.
Or, if we're going to video games only...
Final Fantasy XIV.
Yes, it's an MMO. But, it is one of the most compelling and emotional stories I've experienced in a very long time... and the only one I've ever cared about in an MMO before.
Our villain... Zenos... Oh, how I absolutely ADORE Zenos.
He has several "this is my ultimate attack!" moments, and they all hit like a freight train. But, he's different in the way he uses them.
Everything is just beneath him. All the time. It's all boring. There isn't a fight for him to have that's worth having. Then, he meets you. The Warrior of Light. Someone who can hold their own against him. Someone with power on par with his own. Yep, even if you keep having to bring in 7 other people to stomp him into the ground.
But, then there's his ending. Which, I loved. It made me smile and made me cry.
He tells the player, "I take it, this is your prey? But, why does it still live? Surely, it's no match for you.". Coupled with his line before the final fight with him: "Against you, I need bring my all to bear."
He acknowledges that he needs to throw absolutely everything at you. EVERYTHING. He's been "playing around" up until now. But, that's because that's his motivation. Battle is boring, it's all won so easily. Except with you.
So, this is his "Ultimate Attack". Over and over again. As much as he can throw at you. Everything and ten kitchen sinks.
His final fight against you is an acknowledgement of your power. You're fighting him one on one. No more bringing in 7 other people to fight him as a Boss. You have to solo him.
And when he goes down, he just does one thing for you. He commands you to live. He acknowledges your might, calls you friend, and demands you live.
His ultimate attacks are pure acknowledgement of those things about you, as the player. About you, the character. About the Warrior of Light.
It's wonderful in its execution. And yes, by the end, I called him "friend" too. I weathered him throwing every fiber of his being and every ounce of his energy at me, and maybe a bit more, and I called him friend. Behind my screen, I thanked him for the wonderful time and wished we could do it again sometime, even though we never could.
He gave me everything, because I was worth it to him. My Warrior of Light was worth everything to him.
Is there a better way to have your villain break out "The Ultimate Attack" on you all the time? I don't know. But, I do love how it was executed here.

You know what trope I've gotten a little sick of? Villains who feel justified in what they are doing because of close-minded belief instead of trying to accomplish something by checking to see if their thought process pans out and if the end result makes sense. A villain that screams "freedom is bad, that's where evil comes from!" is boring, a villain that sits down and explains the legitimate problems with things like 'democracy' and 'punishing those who break the rules instead of just not letting them break the rules in the first place' is intriguing. I call this a 'trope' and not 'cliche' because it can be written well, it can make compelling villains, but even done well I just don't care anymore.
One of the unintentionally hilarous things about the movie "2012". Our "villain" was actually reasonable, intelligent, and I found him to be likable. By the end of the movie, I held massive disdain for our heroes and their naive and stupid way of thinking and was cheering our titular villain who said "the ends justify the means" over and over again.
I'd wager that it's pretty hard to write "heroic" protagonists when the villain actually makes sense and points out all the truly terribly crap you and your society are doing.
